Canberra siblings Kate Goodchild and Luke Dorsett have been remembered as kind and selfless at a funeral service to mark their lives which were tragically lost at Dreamworld last month.
While the world was shocked by the horrific accident, which also killed Luke's partner Roozi Araghi and Sydney woman Cindy Low, friends stressed the day was about remembering who they were, not how they died.
Ms Goodchild left behind two little girls, 12-year-old Ebony and eight-month-old Evie, as well as partner of 15 years, David Turner.
The siblings "lived life to the fullest," their uncle Ray Dorsett said at the St Christopher's Cathedral Parish in Canberra's inner-south suburb of Forrest.
"We cannot say how long we will stay here, all we can do is live the best we can in love and joy," he said during their eulogy.
"We can live each day to show those close to us how much we care about them, that they made a difference ... This is how Luke and Kate lived."
He said even a fleeting presence of the brother and sister made a lasting impact on people's lives.
A warm morning and clear sky welcomed mourners who signed a condolence book before filing into the church. Loud speakers were set-up outside the church and an area for media organised on behalf of the family across the road.
A testament to how many lives Mr Dorsett and Ms Goodchild touched, the packed church left the last few to arrive standing outside the doors.
In the eulogy, Ray recalled stories from Kate and Luke's childhood. He described Ms Goodchild as athletic and said she played netball and hockey growing up.
Her 15-year relationship with David Turner, the father of her children, bloomed from a friendship formed in their school years and began with a movie date.
He said they shopped in Canberra to buy their daughter Ebony – who was a "best-dressed child" – an outfit for the wedding they attended in Queensland just days before the tragic accident on the theme park's Thunder River Rapids.
As the ceremony drew to an end, mourners filed out of the church to the soundtrack of One by band U2.
They gathered around the hearse as the coffins were incensed.
Tributes to the siblings and condolences to their families have flowed from the Canberra community since the tragedy.
Mr Dorsett and his partner Mr Araghi were heroes to hundreds of house buyers for winning a legal battle against the ACT government after they were dudded on stamp duty.
Both Ms Goodchild and Mr Dorsett worked for the Department of Human Services, Ms Goodchild at the service centre in Belconnen and Mr Dorsett at the health programs office in Tuggeranong.
The two attended Rosary Primary School in Watson and later St Francis Xavier College in Florey, the school where Ebony is now in year seven.
Their departmental boss, Kathryn Campbell, said the whole department was saddened and will greatly miss the well-liked and respected colleagues.
Ms Goodchild's father, Shayne, recently told media the siblings were extremely close and lived streets away in the north Canberra suburb of Crace.
He said Mr Turner had lost "the love of his life", and his little girls had not only lost their mum but also "two uncles who loved and cherished them".
